Prescription Privileges for Specially Trained Psychologists

Psychologists are scientist-practitioners relying on real evidence and science when treating and evaluating patients. Adding to this training model, I want to share something I’m genuinely excited about that is both a personal and professional milestone that reflects my commitment to the evolving profession of psychology and expands what I hope to one day be able to offer patients in Florida.

In May 2026, I graduated from Fairleigh Dickinson University’s Postdoctoral Master’s Program in Clinical Psychopharmacology, an American Psychological Association’s (APA) designated program that prepares licensed psychologists for prescriptive authority in states where it is permitted. More recently (July 2026), I passed the Psychopharmacology Examination for Psychologists (PEP). The PEP is the national exam required for psychologists to pass who want to prescribe. It is an arduous test covering topics from clinical medicine, neuroscience, laboratory interpretation, general pharmacology to psychopharmacology. Passing it marks another real step forward in building advanced competency in this area. I worked my tail off to complete the program and pass the PEP while running our business, remaining active in the community and with my family, and seeing patients over the last two and a half years. My next step with psychopharmacology is to gain authority to prescribe in Louisiana and New Mexico. I will keep you updated.
